Cool to see, but several issues.
First is that Sanji's supposed powerup visually looks almost exactly like usual Diable Jambe. Makes it not look impressive at all, and had to reread chapter for second time to spot the subtle differences.
Second is, that wasn't a proper fight there once Sanji got serious about finishing the fight, with Queen being entirely distracted.
Third, as cool it was to see for Queen to use all germa tech, what I'm looking forward to is his own inventions and his own strength in battle. Because otherwise it just looks like he's playing with his toys, rather than being serious to start getting his hands dirty with whatever methods to win the fight.
Fourth, the Queen thinking bubbles during his ass whooping is a hope that indeed the fight is far from over. The only argument against so far though - is that Sanji somehow managed to destroy his arm in a single attack. Which set up impression as his further attacks are going to be just as devastating. Maybe and hopefully it was a bait to give that false impression, and now maybe we'll see that Queen is hardly fazed by this supposed new powerup.
